SPRING-HINGE.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application led February 24, 1909. Serial No. 479,706.

To all whom it may concern:

Be it known. that we, FRANCIS BRUCKER and MATTHEW T. LOVE, citizens of the l United States, residing at Shelby, Ohio, have invented certain new and. useful Imi proveniente in Spring-Hinges, ofwhich the j following is a specification. l

Our invention relates to spring hinges, 0f that class shown in an application tiled by Francis Brucker in the United States Pati ent Oiiice, August 1, 1907, and numbered l 388658. j The. improvements herein consist of dej tails of construct-ion of advantage in the operation of the hinges, and in its construction. These. are set forth hereinafter, and are illustrated in the. accompanying dra-wings, in which,

Figure 1 shows the device unattached and in top View; Fig. 2 shows a central longitudinal section of the hinge in place, parts i being in elevation. Figs. 3, Ll and L1 show i details detached and in plan. Fig. 5 reprej sents a slight modification of the. post and floor plate adjustment in side elevation. Fig. 6 shows a plan View of the same with the post in dotted lines, and Fig. 7 shows a rear View.

In these drawings, referring particularly to Fig. 2, the door is indicated at 2, and the floor or base at 8. The frame which holds the working parts is composed of an upper rib 4, and lower rib 5, the upper rib having j a part extending at right angles, and connected to the lower rib at 6. The spring 7 j having it-s adjustable bearing in the turned down end of the upper rib, and the plunger shank 8 inclosed therein with the spring bearing against the shoulders 9, 9, on the shank, are not claimed herein as novel parts j of the combination.

The construction of the frame is new in l this, that the ends of the ribs instead of being brought together, as heretofore, and closing the end of the frame at the edge of j the door, are separated, and one end of the lower rib terminates at the pivot pin 10, I leaving the frame open at its inner end. The lower rib is turned up and terminates i at 5a a little outside the bearing of the axis on which. the door turns. The upper rib 4, i

is in like manner turned down, but beyond this axis is again bent up, so that itsv extremity 4a forms an extended bearing for the edge of the door. The contraction caused by this bending of the ribs reduces the space between them to the proper dimension of the end of the shank 8, and the corresponding end of the arm 11b of the post, and permits a pivot pin 10 carried by said arm to forni the connection between the ribs, at their rear or inner ends.

The hinge post 11 is of improved construction. It has a broad lower bearing 11"' adapted to be seated on the base plate 12, a rear upright part, and an arm 11b, extending from this upright part between the contracted ends. of the ribs. The lowerV forward part of the hinge post has a round projection 13, extending down in axial alinement with the pivot of the post, and adapted to engage with a corresponding hole. in the base plate whereby the part may be rotated for thepurpose of adjustment. The base of the post extends rearward upon the floor plate, and has a broad bearing thereon, and at the rear end extends downward into a recess in the rear end of the plate. The standard or upright part of the post is made stout to support the weight imposed upon it, and has an arm 11b extending forward, fitting between the contracted ends of the ribs. Its forward end carries the pivot pin 10,. and on each side of the pivot is a forwardly proj ecting rounded bearing 11c for the forked head of the shank 8 of the plunger. These bearings tit into corresponding recesses 18 on each side of the head of the shank 8. which has a curved recess to lit the pivot pin. The post is adjusted so that these bearings shall bear on the recesses in the head accurately to hold the door in proper position when closed. The adjustment is effected by means of screws 20, in the base plate, arranged to bear on each side of a, downward projection 11d on the post. A modification of this adjusting means is shown in Figs. 5, 6 and 7. n this, instead of a downward projection the rear end of the post is wider and recessed, as shown at 11X and in the re.- cess is located an. extension 12a of the plate. The adjusting screws 2O pass through the lying walls n each side of the recess and bear on the sides or" the extension.

IVe have provided the hinge with better and more convenient means for connecting it with the door, in this that the upper bar is formed with a tongue, which may be cut from the rib itself and turned up, as shown at 21. It projects forward, and engages with a plate 22, l'ixed in the bottom edge of the door, entering' said plate through a slot 23. The hinge may be made to engage by placing it in proper position and then moving it forward until the tongue passes over the edge of the plate. The parts are held together by means of screws which pass through the extended end Q4 of the lower rib.

It will be observed that the post 1() passes through the ribs where these are brought most nearly together, and is reduced ateach end to receive washers, as indicated at 27, 28, held in place by upsetting the reduced portions ot' the pivot pin. rI`he upper rib has an annular recess around the pivot pin, in which are antifriction rollers, which bear upon a washer 29, resting directly upon the arm of the post. rIhis pivot pin is a section of a plain rod, and, in a simple manner this construction holds rmly the rear ends of the ribs, and permits the arm of the post to enter into its place from the rear, in which place it is held, when the post is seated on the base plate. The shell or casing 30 covers the hinge as in the prior patent hereinbefore referred to. It will be understood that when the door swings in either direction the head of the shank presses upon the rounded bearing of the post arm, causing compression ot' the spring, reaction of which returns the door to its normal position.

IVe claim:

l. In a spring hinge, a frame comprising upper and lower ribs having their rear ends contracted, a post with means for connecting it to the floor, said post having an arm between the contracted portions of the ribs, a pivot pin carried by the post and connecting the ribs, and a spring pressed shank carried wit-hin the frame and bearing against the post, substantially as described.
